Huh.
Without professing to be a WI guru, I find this quite interesting. Based solely upon the calculator provided by DO, I chose to run a 3 GPH nozzle with my kit.
If we assume a maximum of 80% duty cycle on your 550cc injectors, and an actual 7 GPH on your WI system, then your water:fuel ratio is exactly 1:1 at peak load, and greater than that at lesser load. You may be running something other than straight water (like 50% meth) in which case the percentage drops somewhat, but you see where I'm going.
How did you reach the decision to run the 7 GPH nozzle?

I have 4 nozzles, 3,7,10,and 12 gph. I spoke with chance at devils own and we came to the conclusion that i would need 10-12 gph once i really start making power.

Yeah but you could probly wean abit of it off and still be good. You need to find a ballance between your capacity and your consumption. That is why i have a 2 stage system, well that and the drivability issues of a 7gph nozzle at 4 psi would be horrible. You might need a bigger snail for 400 but you will certianly be into the 300's with avengance using your setup.

You've inspired me to do some further research into the subject, and I am finding some evidence to support the use of fuel:water ratios as high as 4:1 for minimum EGT, and given that my "water" is actually 50% "fuel", I am seriously contemplating the use of a larger injection nozzle. Combined with the fact that I'm using a 2d progressive controller, I may be able to get away with quite a lot here.
